New description: [New technical field] This creation involves the field of lighting appliances, especially a technology that can increase the brightness of illumination without increasing the number of light sources and power consumption. [Prior Art] Based on the small size, power saving and long service life, coupled with the improvement of the illuminating brightness technology, LED (light emitting diode) has become more and more popular for lighting applications. Since the LED (four) product is very small, the single (10) luminous lumen can not be compared with the general tungsten filament bulb, fluorescent lamp or existing lighting fixture. Therefore, the current LED lighting fixtures integrate a plurality of Lm) into one LED module. Practical illumination brightness is produced by concentrated illumination. For example, integrating a plurality of LEDs in a specific area of a circuit substrate or a reticle to achieve illumination can achieve the same or even more efficient illumination effect as a general bulb. In addition, the high-power LED input power is only 15~20% converted into light, and the remaining 80~85% is converted into heat. Therefore, the LED module must be equipped with an efficient scatter to properly remove the heat (4) to avoid the LED crystal. The grain interface temperature is too high to affect the luminous efficiency and reduce the luminescence lifetime. For example, a general LE:D lamp structure generally includes a heat sink, a power supply and an LED module; wherein the LE:D module is provided with a plurality of LEDs on a circuit substrate. After the current, it can emit light. The heat sink includes a base and a plurality of fins on the base. The LE1D module is placed on the other side of the pedestal relative to the fin, whereby the heat generated when the LE:D module is energized and illuminated is conducted to each fin 3 M442471 piece, and the airflow is excluded from the heat radiated from the fin . The conventional LED lamp device is provided with an LED module of a required area according to the requirement of brightness, and a required number of LED dies, and a heat sink corresponding to the corresponding area, and a power supply corresponding to the power. The use of LED dies and power supply increases will directly increase manufacturing costs and consume more power. [New content] The purpose of this creation is to solve the problem that the conventional LED lamps must increase the number of LED dies and increase the power supply when they want to increase the brightness of the illumination, so as to increase the disadvantages of manufacturing cost and energy consumption. The feature of the present invention is that an optical cavity disposed between the base of the LED lamp and the light reflecting element and the reticle is configured by the structure of the wire cavity, so that the light source from the LED provided on the pedestal is illuminated by The light reflecting surface of the light reflecting element collects and reflects the required light measurement range by reflection, thereby improving the illumination brightness. The lining means of the creation, the package of money - the pedestal...the light reflecting element, the at least one LED module and the material; the yoke element can be combined with the pedestal-body molding or the independent component 'and the reticle combination-optical a cavity, and the (four) module is disposed on the pedestal in the optical cavity; the light-reflecting element having a slanting symmetry is disposed on opposite sides of the light-emitting direction of the LED or a directional element having a tapered shape in the light-emitting direction of the LED And the inside of the light reflecting element is used as a light reflecting surface. The reticle is combined with the light reflecting element, whereby the light source of the LED light can transmit the angle and shape of the light reflecting element, and the reflecting surface collects and reflects the light. Mosquitoes need to increase the amount of light to enhance the brightness of 4 M442471. The light reflecting element of the present invention may be integrally formed with the base or may be a separate component. The light reflecting element of the present invention may be a cone, so that the LED lamp constitutes a bulb shape. The light reflecting element of the present invention may be a kind of occlusion piece symmetrical with the slanting body of the pedestal body forming body, so that the luminaire constitutes a lamp tube shape. The photographic element of the present invention may be provided with a first-fitting structure, and the photomask may be provided with a second fitting structure, and the first-fitting structure and the second fitting structure may be spliced to form a reticle for the light-reflecting element. The present invention is provided on the light reflecting surface of the light reflecting element, and may be a flat surface or a curved surface. The light reflecting element of the present invention can determine the desired range of enhanced light measurements by selecting the angle and shape through which the reflection is collected via the light reflecting surface.
