Abstract
The utility model discloses a light-emitting diode (LED) daylight lamp and comprises a circuit board, an aluminum substrate and a light guide. The aluminum substrate is arranged on the back side of the circuit board, the longitudinal section of the light guide is between a semi-circle and a 5/6 circle, the inner wall of an opening of the light guide is provided with two guide grooves which are opposite to each other, and the aluminum substrate and the circuit board are arranged in the two guide grooves, the longitudinal section of the light guide is between the semi-circle and the 5/6 circle, compared with a traditional design that the longitudinal section of the light guide is a whole circle, and the light guide saves material and cost and has wider irradiation range than LED daylight lamps which have light guides with arc-shaped longitudinal sections. Under the premise that irradiation intensity is guaranteed, irradiation range is enlarged and cost is reduced. Besides, the back side of the circuit board is provided with the cooling aluminum substrate, accommodating space of the front side of the LED is large, and cooling performance is improved, thereby having popularization and application values.
Description
Technical field
The utility model relates to field of illuminating device, particularly relates to a kind of LED fluorescent lamp.
Background technology
Along with the development of economic society and improving constantly of lighting engineering, the LED fluorescent lamp is widely used in the middle of the daily life because its volume is little, brightness is high and numerous advantages such as energy savings.
Tradition LED fluorescent lamp mainly is made of the circuit board that LED is installed, aluminium base heat sink and light pipe, the longitudinal section of light pipe is generally full circle or less than 1/2 circular arc, if project organization is a full circle, then cost is too high, if project organization be the longitudinal section less than 1/2 circular arc, then the light emitting region of LED fluorescent tube is too little again.
At above-mentioned defective, be necessary the LED fluorescent tube is made improvement.
The utility model content
At the problems referred to above, the utility model provides a kind of good heat dissipation, in light weight and LED fluorescent lamp that range of exposures is wide.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
A kind of LED fluorescent lamp, comprise circuit board, aluminium base and light pipe, described aluminium base is located at the back side of circuit board, it is characterized in that: described light pipe longitudinal section is between semicircle and 5/6 circumference, be provided with two guide grooves on the inwall of light pipe opening part relatively, described aluminium base and circuit board are arranged in two guide grooves.
The beneficial effects of the utility model are: the utility model is as a kind of New LED fluorescent tube, and material and cost for the traditional design that the light pipe longitudinal section is full circle, have been saved in described light pipe longitudinal section between semicircle and 5/6 circumference; The utility model is wider less than the range of exposures of the LED fluorescent lamp of 1/2 circular arc than light pipe longitudinal section again, and under the prerequisite that has guaranteed exposure intensity, range of exposures increases, and cost reduces; In addition, back of circuit board is provided with the heat-radiating aluminum plate, and the front accommodation space is big, and heat dispersion increases, and therefore possesses application value.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model vertical section structure schematic diagram;
Fig. 2 is the utility model overall structure schematic diagram.
The specific embodiment
With reference to Fig. 1-Fig. 2, a kind of LED fluorescent lamp, comprise circuit board 1, aluminium base 2 and light pipe 3, described aluminium base 2 is located at the back side of circuit board 1, described light pipe 3 longitudinal sections are between semicircle and 5/6 circumference, be provided with two guide grooves 4 on the inwall of light pipe 3 opening parts relatively, described aluminium base 2 and circuit board 1 are arranged in two guide grooves 4, and described left and right guide groove 4 distributes axisymmetricly.
The utility model mainly is made of three parts, the front is equipped with the circuit board 1 of LED, the aluminium base 2 that is arranged on circuit board 1 back side and light pipe 3, described aluminium base 2 mainly plays the effect of heat radiation, cost with respect to traditional project organization, not only can well be saved in described light pipe of the present utility model 3 longitudinal sections between semicircle and 5/6 circumference, and range of exposures is bigger, therefore rational in infrastructure, the light and beautiful of the utility model, has good application prospects.
More than preferable enforcement of the present utility model is specified; certainly; the utility model can also adopt form different from the embodiment described above; these do not constitute any restriction to present embodiment; those of ordinary skill in the art should belong in the protection domain of the present utility model conversion of being done under the prerequisite of the utility model spirit that is equal to or corresponding the change.
