New Description: [New Technology Field] This creation is about a light bulb structure with light guiding function, especially one that can promote the utilization of the light source of the bulb and reduce the heat and heat generated by the bulb. The stress caused by the burst is very suitable for various light source module applications that have limited light projection direction and angle requirements. [Prior Art] ^ Some light source facilities that limit the direction and angle of light projection, such as the conventional light source module used in the general machine, as shown in the figure, combine a gas light bulb (1) into a cup. The inside of the reflector (2) is configured to allow the light emitted from the bulb (1) to be projected at an intended projection angle by the reflection of the reflector (2). Since the outgoing light of the f-type bulb (1) is emitted at a nearly full angle of _ condition, some of the emitted light (the dotted line of Fig. 2) will directly scatter the reflector 2) in accordance with the requirement of the projection light (four). The astigmatism that does not contribute to the light-emitting effect is called ineffective light. The generation of no tapping will reduce the brightness of the bulb. In addition, the above-mentioned bulbs will generate extremely high temperatures during operation. In order to avoid the accumulation of thermal energy, the frequency (four) components and the bulb itself are _bad, and generally the fan is used for heat dissipation. However, when the bulb is cooled, it may be hot or cold. The stress generated by the king caused the quartz tube to burst. In order to solve the problem of ineffective light of the above-mentioned conventional light source module, a conventional light bulb structure design with improved light source utilization, as shown in the second figure, is provided with a small reflector on the top of the bulb (3) ( 4), using the small anti-5 M324280 shot mask (4) to reflect the ineffective light (dashed line in the figure) of the bulb (3) to the large reflector (5) on the periphery of the bulb. Another known lamp construction design that enhances the utilization of the light source is to provide a reflective film layer directly on the top of the bulb to reflect the ineffective light of the bulb to the large reflector outside the bulb. The above two conventional bulb design designs that improve the utilization of the light source provide two application options with comparable effects, but both methods also have the quartz tube body that may be caused by the stress generated by the cold and heat process when the bulb is dissipated. The problem of bursting. In view of the above, how to provide another means of supply that is not limited by the conventional patent technology, and can also promote the utilization of the light source of the bulb, and effectively reduce the bursting caused by the stress generated by the hot and cold process of the operating bulb. The design of the light bulb structure is the motivation and technical focus of the design of the case. [New content] The main purpose of this creation is to provide a light bulb structure with a light guiding function, which is applied inside a reflector and uses a light guide. The light guiding member is combined with an outgoing light range at the top of the bulb, and the light guiding member has a light incident surface, a refractive surface, and a light exiting surface. The light-incident surface can be used for a part of the light emitted by the light bulb; the refractive surface can be an optical refractive structure or a reflective film layer for refracting the emitted light toward the light-emitting surface; the light-emitting surface can be a A plane, or a circular arc surface, or an angular corner, is used to effectively project the emitted light to be projected in a predetermined direction. 6

For example, the light source module used in general projectors, the ineffective light portion that would originally directly emit the reflector will pass through this The created light guide is effectively guided to the light exit surface, and then thrown out at the best angle of refraction. Therefore, the effect of promoting the utilization of the light source of the light bulb can be achieved. The above-mentioned light bulb structure having a light guiding function can be formed by cracking a high-temperature resistant material (such as quartz or enamel) having high light transmittance. In this way, the portion of the bulb covered by the light guide member can be insulated from the external portion, so as to reduce the bursting condition caused by the thermal insulation effect and the private stress generated when the heat dissipation of the bulb is reduced. With regard to the main technical contents and implementation effects of the present invention, the following description of the preferred embodiments and the drawings can be disclosed in more detail: "Embodiment 1" Please cooperate with the 3rd and 4th editions. The bulb structure comprises a bulb (2〇) for use with a cup-shaped reflector (1〇), and a light guide (10) for combining a range of light emitted from the top of the bulb (20). The light guiding member (30) is made of a material with good light transmittance and high temperature resistance, and the light guiding member (30) has three components: a light incident surface (31), a refractive surface (32), and a light exit surface (33). Essentials. The person's glossy (31) is used to make the light a part of the outgoing light of (20) is incident; the refracting surface (32) is for refracting the incident light that is incident toward the light emitting surface (33), which may be an optical refractive structure or a reflective film layer; The face (33) may be a plane or a circular arc or an edge 'for projecting the passing light to be effectively projected toward the predetermined 7 M324280 direction. "The above-mentioned light bulb structure having a light guiding function is applied to the need to limit When the light source is used as a general projector, the ineffective light (shown by the dotted line in the legend) that would originally directly emit the reflector (1G): will be the light incident surface of the light guide (10) (31) The injection is then refracted in the direction of the light-emitting surface (33) by the surface (32), and then projected at a predetermined angle of refraction of the light-emitting surface (33), thereby achieving the utilization of the light bulb (2()). In addition, due to the encapsulation function of the light guide member (10), the corresponding portion of the bulb (20) can have the insulation effect of the airflow, and the heat dissipation process is greatly reduced when the bulb (2G) is dissipated. The bursting condition caused by stress. In the above description of the creation embodiment, the light-emitting surface (33) of the light guiding member (3) may be closely adhered or fused with the bulb (2), or may have a slight spacing from the bulb (20). In order to achieve better heat dissipation. Furthermore, the function of the refracting surface (32) is to refract light incident on the light incident surface (31) smoothly and efficiently toward the light exit surface (33). Therefore, the actual application form includes forming the refracting surface (32). The outer peripheral edge of the light guide member (30) is formed on the surface layer other than the human light surface (31) and the light exit surface (33) of the light-emitting member. In summary, it is known that the light bulb structure of the present invention has a light guiding structure, which uses the V-light principle to guide the original invalid light of the bulb to an effective projection range, which is compared with the known method using the reflection principle. The design of the bulb structure to improve the utilization of the light source of the bulb, this creation provides another application choice, and this creation further provides an effective effect of effectively reducing the bursting condition caused by the stress generated by the hot and cold process during the heat dissipation of the bulb.
